Find signed procedures, functions, triggers, assemblies and by which certificates / asymmetric keys

I have created a few Certificates (via CREATE CERTIFICATE ) and Asymmetric Keys (via CREATE ASYMMETRIC KEY ) and used them to sign and counter-sign various SQL modules: - Stored Procedures - User-Defined Functions (UDFs) - Triggers - Assemblies Signing was done via ADD SIGNATURE . But now I need to find which Certificates and/or Asymmetric Keys have been used to sign which particular modules.
